You only showed work for part c). Where is a) and b)?

Never shared them as I know I cocked them up, i need to scrounge a few marks here.? Would you give me any?

Your equation for part a) is correct, but somehow you got the wrong answer. It should be 4.8m.
Part b) is entirely wrong. I would use the law of cosines again to find the angle.
Since a) and b) are wrong, c) is also wrong.

Thanks for that. So she might give me one mark for showing my correct workings?

I would give at most 2 points. Depending on the grader.
